FULL STORY
The discovery of a hybrid population of poplar trees in western Wyoming has provided insight into how natural hybridization informs the evolution of many plant species, according to a team led by Penn State researchers. They also said their discovery suggests that genetic exchange between species may be critical for adaptation to environmental change.The research -- which described a novel lineage of hybrid black cottonwood, or Populus trichocarpa, and balsam poplar, Populus balsamifera, -- was recently published in Molecular Ecology. It is just the latest study to suggest that natural hybridization has played an important role in the evolution of many plant species, according to team leader Jill Hamilton, associate professor in Penn State's College of Agricultural Sciences.
